Thanks Sculpin, excellent review by Robinson. I especially liked the aesthetics of his experience.

“As my four-minute 'ear-filling' began, I at first experienced a warm sensation inside my ears and head unlike any other. It was strangely comforting; I imagined it to be like suddenly finding myself back in my mother's amniotic sac.

The surreal experience continued: first the myriad voices around me chatting started getting farther and farther away almost as if they were purposely lowering their voices to whispers. Then over the course of a minute or so, they disappeared completely. As I sat there with people's mouths moving but not hearing a word, I thought how nice this might be for me to use for a friend who was always talking. But alas, it's only used once (until a new set is needed) in a long while.

Then I could hear my own breathing.

Finally, I could hear my heart beating. Very odd... but nice for a change.”

The good news is that, Sonomax will soon release a wireless Bluetooth version (with a microphone for phone calls) of "eers" and hearing aids. I think they should do that very soon because the hearing aid competition already have.

As you know I’m a hearing aid user and just a month ago I’ve received the latest model with Bluetooth. It communicates (takes and makes calls) with my Blackberry through a Streamer in my shirt pocket even though my phone is maybe 30 feet away.
